Augmented reality with eyewear triggered IoT

ABSTRACT

Systems, devices, media, and methods are presented for an immersive augmented reality (AR) experience using an eyewear device. A portable eyewear device includes a processor, a memory, and a display projected onto at least one lens assembly. The memory has programming stored therein that, when executed by the processor, captures information depicting an environment surrounding the device and identifies a match between objects in that information and predetermined objects in previously obtained information for the same environment. When the position of the eyewear device reaches a preselected location with respect to the matched objects, a physical output is provided to produce the immersive experience. The physical output changes as the position of the eyewear device moves to maintain the immersive experience.

The memory has programming that, whenexecuted by the processor, captures image information for an environmentsurrounding the device, identifies a match between objects in the imageinformation and predetermined objects in previously obtained informationfor the same environment. When the position of the eyewear device withinthe environment reaches a predefined location, the eyewear deviceestablishes communication with a remote device that is capable ofproducing a physical output to deliver an augmented reality experience.Movement of the eyewear device controls the physical output. Examplephysical output includes interacting with a displayed scene, turning onan air flow device (e.g., a fan to give a puff of air that turns a pagein a book), and emitting sound from a speaker. The eyewear device mayadditionally display augmented reality image overlays that coincide withthe physical output to further enhance the augmented reality experience.

Reference now is made in detail to the examples illustrated in theaccompanying drawings and discussed below.

FIG. 1A is a side view (right) of an example hardware configuration ofan eyewear device 100 which includes a touch-sensitive input device ortouchpad 181. As shown, the touchpad 181 may have a boundary that issubtle and not easily seen; alternatively, the boundary may be plainlyvisible and may include a raised or otherwise tactile edge that providesfeedback to the user about the location and boundary of the touchpad181. In other examples, the eyewear 100 may include a touchpad on theleft side.

The surface of the touchpad 181 is configured to detect finger touches,taps, and gestures (e.g., moving touches) for use with a GUI displayedby the eyewear, on an image display, to allow the user to navigatethrough and select menu options in an intuitive manner, which enhancesand simplifies the user experience.

Detection of finger inputs on the touchpad 181 can enable severalfunctions. For example, touching anywhere on the touchpad 181 may causethe GUI to display or highlight an item on the image display, which maybe projected onto at least one of the optical assemblies 180A, 180B.Double tapping on the touchpad 181 may select an item or icon. Slidingor swiping a finger in a particular direction (e.g., from front to back,back to front, up to down, or down to) may cause the items or icons toslide or scroll in a particular direction; for example, to move to anext item, icon, video, image, page, or slide. Sliding the finger inanother direction may slide or scroll in the opposite direction; forexample, to move to a previous item, icon, video, image, page, or slide.The touchpad 181 can be virtually anywhere on the eyewear device 100.

In one example, an identified finger gesture of a single tap on thetouchpad 181, initiates selection or pressing of a graphical userinterface element in the image presented on the image display of theoptical assembly 180A, 180B. An adjustment to the image presented on theimage display of the optical assembly 180A, 180B based on the identifiedfinger gesture can be a primary action which selects or submits thegraphical user interface element on the image display of the opticalassembly 180A, 180B for further display or execution.

As shown, the eyewear 100 includes a right visible-light camera 114B. Asfurther described herein, two cameras 114A, 114B capture imageinformation for a scene from two separate viewpoints. The two capturedimages may be used to project a three-dimensional display onto an imagedisplay for viewing with 3D glasses.

The eyewear device 100 includes a right optical assembly 180B with animage display to present images, such as depth images. As shown in FIGS.1A and 1B, the eyewear device 100 includes the right visible-lightcamera 114B. The eyewear device 100 can include multiple visible-lightcameras 114A, 114B that form a passive type of three-dimensional camera,such as stereo camera, of which the right visible-light camera 114B islocated on a right corner 110B. As shown in FIGS. 1C-D, the eyeweardevice 100 also includes a left visible-light camera 114A.

Left and right visible-light cameras 114A, 114B are sensitive to thevisible-light range wavelength. Each of the visible-light cameras 114A,114B have a different frontward facing field of view which areoverlapping to enable generation of three-dimensional depth images, forexample, right visible-light camera 114B depicts a right field of view111B. Generally, a “field of view” is the part of the scene that isvisible through the camera at a particular position and orientation inspace. The fields of view 111A and 111B have an overlapping field ofview 304 (FIG. 3 ). Objects or object features outside the field of view111A, 111B when the visible-light camera captures the image are notrecorded in a raw image (e.g., photograph or picture). The field of viewdescribes an angle range or extent, which the image sensor of thevisible-light camera 114A, 114B picks up electromagnetic radiation of agiven scene in a captured image of the given scene. Field of view can beexpressed as the angular size of the view cone, i.e., an angle of view.The angle of view can be measured horizontally, vertically, ordiagonally.

In an example, visible-light cameras 114A, 114B have a field of viewwith an angle of view between 15° to 30°, for example 24°, and have aresolution of 480×480 pixels. The “angle of coverage” describes theangle range that a lens of visible-light cameras 114A, 114B or infraredcamera 410 (see FIG. 4A) can effectively image. Typically, the cameralens produces an image circle that is large enough to cover the film orsensor of the camera completely, possibly including some vignetting(e.g., a darkening of the image toward the edges when compared to thecenter). If the angle of coverage of the camera lens does not fill thesensor, the image circle will be visible, typically with strongvignetting toward the edge, and the effective angle of view will belimited to the angle of coverage.

Examples of such visible-light cameras 114A, 114B include ahigh-resolution complementary metal-oxide-semiconductor (CMOS) imagesensor and a digital VGA camera (video graphics array) capable ofresolutions of 640p (e.g., 640×480 pixels for a total of 0.3megapixels), 720p, or 1080p. Other examples of visible-light cameras114A, 114B that can capture high-definition (HD) still images and storethem at a resolution of 1642 by 1642 pixels (or greater); or recordhigh-definition video at a high frame rate (e.g., thirty to sixty framesper second or more) and store the recording at a resolution of 1216 by1216 pixels (or greater).

The eyewear device 100 may capture image sensor data from thevisible-light cameras 114A, 114B along with geolocation data, digitizedby an image processor, for storage in a memory. The visible-lightcameras 114A, 114B capture respective left and right raw images in thetwo-dimensional space domain that comprise a matrix of pixels on atwo-dimensional coordinate system that includes an X-axis for horizontalposition and a Y-axis for vertical position. Each pixel includes a colorattribute value (e.g., a red pixel light value, a green pixel lightvalue, or a blue pixel light value); and a position attribute (e.g., anX-axis coordinate and a Y-axis coordinate).

In order to capture stereo images for later display as athree-dimensional projection, the image processor 412 (shown in FIG. 4A)may be coupled to the visible-light cameras 114A, 114B to receive andstore the visual image information. The image processor 412 or anotherprocessor, which controls operation of the visible-light cameras 114A,114B to act as a stereo camera simulating human binocular vision, mayadd a timestamp to each image. The timestamp on each pair of imagesallows display of the images together as part of a three-dimensionalprojection. Three-dimensional projections produce an immersive,life-like experience that is desirable in a variety of contexts,including virtual reality (VR) and video gaming.

FIG. 3 is a diagrammatic depiction of a three-dimensional scene 306, aleft raw image 302A captured by a left visible-light camera 114A, and aright raw image 302B captured by a right visible-light camera 114B. Theleft field of view 111A may overlap, as shown, with the right field ofview 111B. The overlapping field of view 304 represents that portion ofthe image captured by both cameras 114A, 114B. The term ‘overlapping’when referring to field of view means the matrix of pixels in thegenerated raw images overlap by thirty percent (30%) or more.‘Substantially overlapping’ means the matrix of pixels in the generatedraw images—or in the infrared image of scene—overlap by fifty percent(50%) or more. As described herein, the two raw images 302A, 302B may beprocessed to include a timestamp, which allows the images to bedisplayed together as part of a three-dimensional projection.

For the capture of stereo images, as illustrated in FIG. 3 , a pair ofraw red, green, and blue (RGB) images are captured of a real scene 306at a given moment in time—a left raw image 302A captured by the leftcamera 114A and right raw image 302B captured by the right camera 114B.When the pair of raw images 302A, 302B are processed (e.g., by the imageprocessor 412), depth images are generated. The generated depth imagesmay be viewed on an optical assembly 180A, 180B of an eyewear device, onanother display (e.g., the image display 580 on a mobile device 401), oron a screen.

The generated depth images are in the three-dimensional space domain andcan comprise a matrix of vertices on a three-dimensional locationcoordinate system that includes an X axis for horizontal position (e.g.,length), a Y axis for vertical position (e.g., height), and a Z axis fordepth (e.g., distance). Each vertex may include a color attribute (e.g.,a red pixel light value, a green pixel light value, or a blue pixellight value); a position attribute (e.g., an X location coordinate, a Ylocation coordinate, and a Z location coordinate); a texture attribute;a reflectance attribute; or any combination thereof. The textureattribute quantifies the perceived texture of the depth image, such asthe spatial arrangement of color or intensities in a region of verticesof the depth image.

In one example, the eyewear device 100 includes a frame 105, a lefttemple 110A extending from a left lateral side 170A of the frame 105,and a right temple 125B extending from a right lateral side 170B of theframe 105. The left camera 114A is connected to the frame 105, the lefttemple 125B, or the left corner 110A to capture a left raw image 302Afrom the left side of scene 306. The right camera 114B is connected tothe frame 105, the right corner 110A, or the right temple 125B tocapture a right raw image 302B from the right side of scene 306.

FIG. 1B is a top cross-sectional view of a right corner 110B of theeyewear device 100 of FIG. 1A depicting the right visible-light camera114B of the camera system, and a circuit board. FIG. 1C is a side view(left) of an example hardware configuration of an eyewear device 100 ofFIG. 1A, which shows a left visible-light camera 114A of the camerasystem. FIG. 1D is a top cross-sectional view of a left corner 110A ofthe eyewear device of FIG. 1C depicting the left visible-light camera114A of the three-dimensional camera, and a circuit board. Constructionand placement of the left visible-light camera 114A is substantiallysimilar to the right visible-light camera 114B, except the connectionsand coupling are on the left lateral side 170A. As shown in the exampleof FIG. 1B, the eyewear device 100 includes the right visible-lightcamera 114B and a circuit board 140B, which may be a flexible printedcircuit board (PCB). The right hinge 126B connects the right corner 110Bto a right temple 125B of the eyewear device 100. In some examples,components of the right visible-light camera 114B, the flexible PCB140B, or other electrical connectors or contacts may be located on theright temple 125B or the right hinge 126B.

The right corner 110B includes corner body 190 and a corner cap, withthe corner cap omitted in the cross-section of FIG. 1B. Disposed insidethe right corner 110B are various interconnected circuit boards, such asPCBs or flexible PCBs, that include controller circuits for rightvisible-light camera 114B, microphone(s), low-power wireless circuitry(e.g., for wireless short range network communication via Bluetooth™),high-speed wireless circuitry (e.g., for wireless local area networkcommunication via WiFi).

The right visible-light camera 114B is coupled to or disposed on theflexible PCB 140B and covered by a visible-light camera cover lens,which is aimed through opening(s) formed in the frame 105. For example,the right rim 107B of the frame 105, shown in FIG. 2A, is connected tothe right corner 110B and includes the opening(s) for the visible-lightcamera cover lens. The frame 105 includes a front side configured toface outward and away from the eye of the user. The opening for thevisible-light camera cover lens is formed on and through the front oroutward-facing side of the frame 105. In the example, the rightvisible-light camera 114B has an outward-facing field of view 111B(shown in FIG. 3 ) with a line of sight or perspective that iscorrelated with the right eye of the user of the eyewear device 100. Thevisible-light camera cover lens can also be adhered to a front side oroutward-facing surface of the right corner 110B in which an opening isformed with an outward-facing angle of coverage, but in a differentoutwardly direction. The coupling can also be indirect via interveningcomponents.

As shown in FIG. 1B, flexible PCB 140B is disposed inside the rightcorner 110B and is coupled to one or more other components housed in theright corner 110B. Although shown as being formed on the circuit boardsof the right corner 110B, the right visible-light camera 114B can beformed on the circuit boards of the left corner 110A, the temples 125A,125B, or the frame 105.

FIGS. 2A and 2B are perspective views, from the rear, of examplehardware configurations of the eyewear device 100, including twodifferent types of image displays. The eyewear device 100 is sized andshaped in a form configured for wearing by a user; the form ofeyeglasses is shown in the example. The eyewear device 100 can takeother forms and may incorporate other types of frameworks; for example,a headgear, a headset, or a helmet.

In the eyeglasses example, eyewear device 100 includes a frame 105including a left rim 107A connected to a right rim 107B via a bridge 106adapted to be supported by a nose of the user. The left and right rims107A, 107B include respective apertures 175A, 175B, which hold arespective optical element 180A, 180B, such as a lens and a displaydevice. As used herein, the term “lens” is meant to include transparentor translucent pieces of glass or plastic having curved or flat surfacesthat cause light to converge/diverge or that cause little or noconvergence or divergence.

Although shown as having two optical elements 180A, 180B, the eyeweardevice 100 can include other arrangements, such as a single opticalelement (or it may not include any optical element 180A, 180B),depending on the application or the intended user of the eyewear device100. As further shown, eyewear device 100 includes a left corner 110Aadjacent the left lateral side 170A of the frame 105 and a right corner110B adjacent the right lateral side 170B of the frame 105. The corners110A, 110B may be integrated into the frame 105 on the respective sides170A, 170B (as illustrated) or implemented as separate componentsattached to the frame 105 on the respective sides 170A, 170B.Alternatively, the corners 110A, 110B may be integrated into temples(not shown) attached to the frame 105.

In one example, the image display of optical assembly 180A, 180Bincludes an integrated image display. As shown in FIG. 2A, each opticalassembly 180A, 180B includes a suitable display matrix 177, such as aliquid crystal display (LCD), an organic light-emitting diode (OLED)display, or any other such display. Each optical assembly 180A, 180Balso includes an optical layer or layers 176, which can include lenses,optical coatings, prisms, mirrors, waveguides, optical strips, and otheroptical components in any combination. The optical layers 176A, 176B, .. . 176N (shown as 176A-N in FIG. 2A and herein) can include a prismhaving a suitable size and configuration and including a first surfacefor receiving light from a display matrix and a second surface foremitting light to the eye of the user. The prism of the optical layers176A-N extends over all or at least a portion of the respectiveapertures 175A, 175B formed in the left and right rims 107A, 107B topermit the user to see the second surface of the prism when the eye ofthe user is viewing through the corresponding left and right rims 107A,107B. The first surface of the prism of the optical layers 176A-N facesupwardly from the frame 105 and the display matrix 177 overlies theprism so that photons and light emitted by the display matrix 177impinge the first surface. The prism is sized and shaped so that thelight is refracted within the prism and is directed toward the eye ofthe user by the second surface of the prism of the optical layers176A-N. In this regard, the second surface of the prism of the opticallayers 176A-N can be convex to direct the light toward the center of theeye. The prism can optionally be sized and shaped to magnify the imageprojected by the display matrix 177, and the light travels through theprism so that the image viewed from the second surface is larger in oneor more dimensions than the image emitted from the display matrix 177.

In one example, the optical layers 176A-N may include an LCD layer thatis transparent (keeping the lens open) unless and until a voltage isapplied which makes the layer opaque (closing or blocking the lens). Theimage processor 412 on the eyewear device 100 may execute programming toapply the voltage to the LCD layer in order to produce an active shuttersystem, making the eyewear device 100 suitable for viewing visualcontent when displayed as a three-dimensional projection. Technologiesother than LCD may be used for the active shutter mode, including othertypes of reactive layers that are responsive to a voltage or anothertype of input.

In another example, the image display device of optical assembly 180A,180B includes a projection image display as shown in FIG. 2B. Eachoptical assembly 180A, 180B includes a laser projector 150, which is athree-color laser projector using a scanning mirror or galvanometer.During operation, an optical source such as a laser projector 150 isdisposed in or on one of the temples 125A, 125B of the eyewear device100. Optical assembly 180B in this example includes one or more opticalstrips 155A, 155B, . . . 155N (shown as 155A-N in FIG. 2B) which arespaced apart and across the width of the lens of each optical assembly180A, 180B or across a depth of the lens between the front surface andthe rear surface of the lens.

As the photons projected by the laser projector 150 travel across thelens of each optical assembly 180A, 180B, the photons encounter theoptical strips 155A-N. When a particular photon encounters a particularoptical strip, the photon is either redirected toward the user's eye, orit passes to the next optical strip. A combination of modulation oflaser projector 150, and modulation of optical strips, may controlspecific photons or beams of light. In an example, a processor controlsoptical strips 155A-N by initiating mechanical, acoustic, orelectromagnetic signals. Although shown as having two optical assemblies180A, 180B, the eyewear device 100 can include other arrangements, suchas a single or three optical assemblies, or each optical assembly 180A,180B may have arranged different arrangement depending on theapplication or intended user of the eyewear device 100.

As further shown in FIGS. 2A and 2B, eyewear device 100 includes a leftcorner 110A adjacent the left lateral side 170A of the frame 105 and aright corner 110B adjacent the right lateral side 170B of the frame 105.The corners 110A, 110B may be integrated into the frame 105 on therespective lateral sides 170A, 170B (as illustrated) or implemented asseparate components attached to the frame 105 on the respective sides170A, 170B. Alternatively, the corners 110A, 110B may be integrated intotemples 125A, 125B attached to the frame 105.

In another example, the eyewear device 100 shown in FIG. 2B may includetwo projectors, a left projector 150A (not shown) and a right projector150B (shown as projector 150). The left optical assembly 180A mayinclude a left display matrix 177A (not shown) or a left set of opticalstrips 155′A, 155′B, . . . 155′N (155 prime, A through N, not shown)which are configured to interact with light from the left projector150A. Similarly, the right optical assembly 180B may include a rightdisplay matrix 177B (not shown) or a right set of optical strips 155″A,155″B, . . . 155″N (155 double-prime, A through N, not shown) which areconfigured to interact with light from the right projector 150B. In thisexample, the eyewear device 100 includes a left display and a rightdisplay.

FIG. 4A is a functional block diagram of an example augmented realitysystem 400 including a wearable device (e.g., an eyewear device 100),another electronic device 402, a mobile device 401, and a server system498 connected via various networks 495 such as the Internet. The system400 includes a low-power wireless connection 425 and a high-speedwireless connection 437 between the eyewear device 100 and a mobiledevice 401—and, in some examples, as shown, between the eyewear device100 and the other electronic device 402.

In one example, the other electronic device 402 is a remote device thatmay be a “smart device” (also referred to as an IoT device) including apower supply 652 (separate from that of the eyewear device), amicrocontroller 656 or processor, a high-speed network connection 654, amemory 658, and physical output devices 662 (such as, for example,illumination sources, airflow sources, etc.) (shown in FIG. 4C).

As shown in FIG. 4A, the eyewear device 100 includes one or morevisible-light cameras 114A, 114B that capture still images or video, asdescribed herein. The cameras 114A, 114B may have a direct memory access(DMA) to high-speed circuitry 430 and function as a stereo camera. Thecameras 114A, 114B may be used to capture initial-depth images forrendering three-dimensional (3D) models that are texture-mapped imagesof a red, green, and blue (RGB) imaged scene. The device 100 may alsoinclude a depth sensor, which uses infrared signals to estimate theposition of objects relative to the device 100. The depth sensor in someexamples includes one or more infrared emitter(s) 415 and infraredcamera(s) 410. The cameras and the depth sensor are non-limitingexamples of sensors in the eyewear device 100.

The eyewear device 100 further includes two image displays of eachoptical assembly 180A, 180B (one associated with the left side 170A andone associated with the right side 170B). The eyewear device 100 alsoincludes an image display driver 442, an image processor 412, low-powercircuitry 420, and high-speed circuitry 430. The image displays of eachoptical assembly 180A, 180B are for presenting images, including stillimages or video. The image display driver 442 is coupled to the imagedisplays of each optical assembly 180A, 180B in order to control thedisplay of images.

The components shown in FIG. 4A for the eyewear device 100 are locatedon one or more circuit boards, for example, a printed circuit board(PCB) or flexible printed circuit (FPC), located in the rims or temples.Alternatively, or additionally, the depicted components can be locatedin the corners, frames, hinges, or bridge of the eyewear device 100.Left and right visible-light cameras 114A, 114B can include digitalcamera elements such as a complementary metal-oxide-semiconductor (CMOS)image sensor, a charge-coupled device, a lens, or any other respectivevisible or light capturing elements that may be used to capture data,including still images or video of scenes with unknown objects.

As shown in FIG. 4A, high-speed circuitry 430 includes a high-speedprocessor 432, a memory 434, and high-speed wireless circuitry 436. Inthe example, the image display driver 442 is coupled to the high-speedcircuitry 430 and operated by the high-speed processor 432 in order todrive the left and right image displays of each optical assembly 180A,180B. High-speed processor 432 may be any processor capable of managinghigh-speed communications and operation of any general computing systemneeded for eyewear device 100. High-speed processor 432 includesprocessing resources needed for managing high-speed data transfers onhigh-speed wireless connection 437 to a wireless local area network(WLAN) using high-speed wireless circuitry 436.

In some examples, the high-speed processor 432 executes an operatingsystem such as a LINUX operating system or other such operating systemof the eyewear device 100 and the operating system is stored in memory434 for execution. In addition to any other responsibilities, thehigh-speed processor 432 executes a software architecture for theeyewear device 100 that is used to manage data transfers with high-speedwireless circuitry 436. In some examples, high-speed wireless circuitry436 is configured to implement Institute of Electrical and ElectronicEngineers (IEEE) 802.11 communication standards, also referred to hereinas Wi-Fi. In other examples, other high-speed communications standardsmay be implemented by high-speed wireless circuitry 436.

The low-power circuitry 420 includes a low-power processor 422 andlow-power wireless circuitry 424. The low-power wireless circuitry 424and the high-speed wireless circuitry 436 of the eyewear device 100 caninclude short-range transceivers (Bluetooth™ or Bluetooth Low-Energy(BLE)) and wireless wide, local, or wide-area network transceivers(e.g., cellular or WiFi). Mobile device 401, including the transceiverscommunicating via the low-power wireless connection 425 and thehigh-speed wireless connection 437, may be implemented using details ofthe architecture of the eyewear device 100, as can other elements of thenetwork 495.

Although the memory 434 is shown as integrated withhigh-speed circuitry 430, the memory 434 in other examples may be anindependent, standalone element of the eyewear device 100. In certainsuch examples, electrical routing lines may provide a connection througha chip that includes the high-speed processor 432 from the imageprocessor 412 or low-power processor 422 to the memory 434. In otherexamples, the high-speed processor 432 may manage addressing of memory434 such that the low-power processor 422 will boot the high-speedprocessor 432 any time that a read or write operation involving memory434 is needed.

As shown in FIG. 4A, the high-speed processor 432 of the eyewear device100 can be coupled to the camera system (visible-light cameras 114A,114B), the image display driver 442, the user input device 491, and thememory 434. As shown in FIG. 5 , the CPU 530 of the mobile device 401may be coupled to a camera system 570, a mobile display driver 582, auser input layer 891, and a memory 540A.

The server system 498 may be one or more computing devices as part of aservice or network computing system, for example, that include aprocessor, a memory, and network communication interface to communicateover the network 495 with an eyewear device 100 and a mobile device 401.

The output components of the eyewear device 100 include visual elements,such as the left and right image displays associated with each lens oroptical assembly 180A, 180B as described in FIGS. 2A and 2B (e.g., adisplay such as a liquid crystal display (LCD), a plasma display panel(PDP), a light emitting diode (LED) display, a projector, or awaveguide). The eyewear device 100 may include a user-facing indicator(e.g., an LED, a loudspeaker, or a vibrating actuator), anoutward-facing signal (e.g., an LED, a loudspeaker), or both. The imagedisplays of each optical assembly 180A, 180B are driven by the imagedisplay driver 442. In some example configurations, the outputcomponents of the eyewear device 100 further include additionalindicators such as audible elements (e.g., loudspeakers), tactilecomponents (e.g., an actuator such as a vibratory motor to generatehaptic feedback), and other signal generators. For example, the device100 may include a user-facing set of indicators, and an outward-facingset of signals. The user-facing set of indicators are configured to beseen or otherwise sensed by the user of the device 100. For example, thedevice 100 may include an LED display positioned so the user can see it,one or more speakers positioned to generate a sound the user can hear,or an actuator to provide haptic feedback the user can feel. Theoutward-facing set of signals are configured to be seen or otherwisesensed by an observer near the device 100. Similarly, the device 100 mayinclude an LED, a loudspeaker, or an actuator that is configured andpositioned to be sensed by an observer.

The input components of the eyewear device 100 may include alphanumericinput components (e.g., a touch screen or touchpad configured to receivealphanumeric input, a photo-optical keyboard, or otheralphanumeric-configured elements), pointer-based input components (e.g.,a mouse, a touchpad, a trackball, a joystick, a motion sensor, or otherpointing instruments), tactile input components (e.g., a button switch,a touch screen or touchpad that senses the location, force or locationand force of touches or touch gestures, or other tactile-configuredelements), and audio input components (e.g., a microphone), and thelike. The mobile device 401 and the server system 498 may includealphanumeric, pointer-based, tactile, audio, and other input components.

In some examples, the eyewear device 100 includes a collection ofmotion-sensing components referred to as an inertial measurement unit472. The motion-sensing components may be micro-electro-mechanicalsystems (MEMS) with microscopic moving parts, often small enough to bepart of a microchip. The inertial measurement unit (IMU) 472 in someexample configurations includes an accelerometer, a gyroscope, and amagnetometer. The accelerometer senses the linear acceleration of thedevice 100 (including the acceleration due to gravity) relative to threeorthogonal axes (x, y, z). The gyroscope senses the angular velocity ofthe device 100 about three axes of rotation (pitch, roll, yaw).Together, the accelerometer and gyroscope can provide position,orientation, and motion data about the device relative to six axes (x,y, z, pitch, roll, yaw). The magnetometer, if present, senses theheading of the device 100 relative to magnetic north. Additionally, oralternatively, the position of the eyewear device 100 may be determinedby comparing images captured by, for example, cameras 114 and comparingthose images to previously captured images having known positionalinformation. Thus, the position of the device 100 may be determined bylocation sensors, such as image information gathered by cameras 114, aGPS receiver, one or more transceivers to generate relative positioncoordinates, altitude sensors, barometers, or other orientation sensors.Such positioning system coordinates can also be received over thewireless connections 425, 437 from the mobile device 401 via thelow-power wireless circuitry 424 or the high-speed wireless circuitry436.

The IMU 472 may include or cooperate with a digital motion processor orprogramming that gathers the raw data from the components and compute anumber of useful values about the position, orientation, and motion ofthe device 100. For example, the acceleration data gathered from theaccelerometer can be integrated to obtain the velocity relative to eachaxis (x, y, z); and integrated again to obtain the position of thedevice 100 (in linear coordinates, x, y, and z). The angular velocitydata from the gyroscope can be integrated to obtain the position of thedevice 100 (in spherical coordinates). The programming for computingthese useful values may be stored in memory 434 and executed by thehigh-speed processor 432 of the eyewear device 100.

The eyewear device 100 may optionally include additional peripheralsensors, such as biometric sensors, specialty sensors, or displayelements integrated with eyewear device 100. For example, peripheraldevice elements may include any I/O components including outputcomponents, motion components, position components, or any other suchelements described herein. For example, the biometric sensors mayinclude components to detect expressions (e.g., hand expressions, facialexpressions, vocal expressions, body gestures, or eye tracking), tomeasure biosignals (e.g., blood pressure, heart rate, body temperature,perspiration, or brain waves), or to identify a person (e.g.,identification based on voice, retina, facial characteristics,fingerprints, or electrical biosignals such as electroencephalogramdata), and the like.

The mobile device 401 may be a smartphone, tablet, laptop computer,access point, or any other such device capable of connecting witheyewear device 100 using both a low-power wireless connection 425 and ahigh-speed wireless connection 437. Mobile device 401 is connected toserver system 498 and network 495. The network 495 may include anycombination of wired and wireless connections.

In some examples, the devices 100, 401, 402 illustrated in FIG. 4A areconfigured to cooperate and share the processing demand when performingany of the functions described herein. For example, the other electronicdevice 402, may be configured to detect an interaction, such as awireless signal from the device 100, and process the interaction todetermine relative proximity. If within a predefined range, theelectronic device 402 sends an application programming interface (API)to the eyewear device 100, at which point the eyewear device 100 takesover the task of performing additional functions. Additional functionsmay also be performed by the mobile device 401. In this aspect, theaugmented reality system 400 distributes, shares, and manages theprocessing demand such that the functions described herein are performedefficiently and effectively.

The augmented reality system 400, as shown in FIG. 4A, includes acomputing device, such as mobile device 401, coupled to an eyeweardevice 100 and another remote electronic device 402 over a network. Theaugmented reality system 400 includes a memory for storing instructionsand a processor for executing the instructions. Execution of theinstructions of the augmented reality system 400 by the processor 432configures the eyewear device 100 to cooperate with the other electronicdevice 402 or the mobile device 401. The system 400 may utilize thememory 434 of the eyewear device 100 or the memory elements 540A, 540B,540C of the mobile device 401 (FIG. 5 ) or the memory 630 of the otherelectronic device 402 (FIG. 6 ). Also, the system 400 may utilize theprocessor elements 432, 422 of the eyewear device 100 or the centralprocessing unit (CPU) 540 of the mobile device 401 (FIG. 5 ) or themicroprocessor 656 of the other electronic device 402. In addition, thesystem 400 may further utilize the memory and processor elements of theserver system 498. In this aspect, the memory and processing functionsof the augmented reality system 400 can be shared or distributed acrossthe eyewear device 100, the mobile device 401, the other electronicdevice 402, or the server system 498.

In some examples, a portion of the memory 434 is used to store an objectdatabase 480 (see FIG. 4B) while another portion of the memory 434 hasprogramming stored therein, which when executed by the processor 432provides an object identifier 482 (see FIG. 4B). The flowchart shown inFIG. 4B illustrates such an example.

In some examples, the object database 480 is initially stored in amemory of the server system 498 and the memory 434 has programmingstored in, which when executed by the processor 432 causes the eyeweardevice to access the server system 498, retrieve all or a portion of theobject database 480 from the server system 498 and store the retrievedobject database 480 in the memory 434.

FIG. 5 is a high-level functional block diagram of an example mobiledevice 401. Mobile device 401 includes a flash memory 540A that storesprogramming to be executed by the CPU 530 to perform all or a subset ofthe functions described herein.

The mobile device 401 may include a camera 570 that comprises at leasttwo visible-light cameras (first and second visible-light cameras withoverlapping fields of view) or at least one visible-light camera and adepth sensor with substantially overlapping fields of view. Flash memory540A may further include multiple images or video, which are generatedvia the camera 570.

As shown, the mobile device 401 includes an image display 580, a mobiledisplay driver 582 to control the image display 580, and a controller584. In the example of FIG. 5 , the image display 580 includes a userinput layer 591 (e.g., a touchscreen) that is layered on top of orotherwise integrated into the screen used by the image display 580.

Examples of touchscreen-type mobile devices that may be used include(but are not limited to) a smart phone, a personal digital assistant(PDA), a tablet computer, a laptop computer, or other portable device.The structure and operation of the touchscreen-type devices are providedby way of example and the subject technology as described herein is notintended to be limited thereto. For purposes of this discussion, FIG. 5therefore provides a block diagram illustration of the example mobiledevice 401 with a user interface that includes a touchscreen input layer591 for receiving input (by touch, multi-touch, or gesture, and thelike, by hand, stylus or other tool) and an image display 580 fordisplaying content.

As shown in FIG. 5 , the mobile device 401 includes at least one digitaltransceiver (XCVR) 510, shown as WWAN XCVRs, for digital wirelesscommunications via a wide-area wireless mobile communication network.The mobile device 401 also includes additional digital or analogtransceivers, such as short-range transceivers (XCVRs) 520 forshort-range network communication, such as via NFC, VLC, DECT, ZigBee,Bluetooth™, or WiFi. For example, short range XCVRs 520 may take theform of any available two-way wireless local area network (WLAN)transceiver of a type that is compatible with one or more standardprotocols of communication implemented in wireless local area networks,such as one of the Wi-Fi standards under IEEE 802.11.

To generate location coordinates for positioning of the mobile device401, the mobile device 401 can include image-based location systems anda global positioning system (GPS) receiver. Alternatively, oradditionally, the mobile device 401 can utilize either or both the shortrange XCVRs 520 and WWAN XCVRs 510 for generating location coordinatesfor positioning. For example, cellular network, Wi-Fi, or Bluetooth™based positioning systems can generate very accurate locationcoordinates, particularly when used in combination. Such locationcoordinates can be transmitted to the eyewear device over one or morenetwork connections via XCVRs 510, 520.

The transceivers 510, 520 (i.e., the network communication interface)conforms to one or more of the various digital wireless communicationstandards utilized by modern mobile networks. Examples of WWANtransceivers 510 include (but are not limited to) transceiversconfigured to operate in accordance with Code Division Multiple Access(CDMA) and 3rd Generation Partnership Project (3GPP) networktechnologies including, for example and without limitation, 3GPP type 2(or 3GPP2) and LTE, at times referred to as “4G.” For example, thetransceivers 510, 520 provide two-way wireless communication ofinformation including digitized audio signals, still image and videosignals, web page information for display as well as web-related inputs,and various types of mobile message communications to/from the mobiledevice 401.

The mobile device 401 further includes a microprocessor that functionsas a central processing unit (CPU); shown as CPU 530 in FIG. 5 . Aprocessor is a circuit having elements structured and arranged toperform one or more processing functions, typically various dataprocessing functions. Although discrete logic components could be used,the examples utilize components forming a programmable CPU. Amicroprocessor for example includes one or more integrated circuit (IC)chips incorporating the electronic elements to perform the functions ofthe CPU. The CPU 530, for example, may be based on any known oravailable microprocessor architecture, such as a Reduced Instruction SetComputing (RISC) using an ARM architecture, as commonly used today inmobile devices and other portable electronic devices. Of course, otherarrangements of processor circuitry may be used to form the CPU 530 orprocessor hardware in smartphone, laptop computer, and tablet.

The CPU 530 serves as a programmable host controller for the mobiledevice 401 by configuring the mobile device 401 to perform variousoperations, for example, in accordance with instructions or programmingexecutable by CPU 530. For example, such operations may include variousgeneral operations of the mobile device, as well as operations relatedto the programming for applications on the mobile device. Although aprocessor may be configured by use of hardwired logic, typicalprocessors in mobile devices are general processing circuits configuredby execution of programming.

The mobile device 401 includes a memory or storage system, for storingprogramming and data. In the example, the memory system may include aflash memory 540A, a random-access memory (RAM) 540B, and other memorycomponents 540C, as needed. The RAM 540B serves as short-term storagefor instructions and data being handled by the CPU 530, e.g., as aworking data processing memory. The flash memory 540A typically provideslonger-term storage.

Hence, in the example of mobile device 401, the flash memory 540A isused to store programming or instructions for execution by the CPU 530.Depending on the type of device, the mobile device 401 stores and runs amobile operating system through which specific applications areexecuted. Examples of mobile operating systems include Google Android,Apple iOS (for iPhone or iPad devices), Windows Mobile, Amazon Fire OS,RIM BlackBerry OS, or the like.

The processor 432 within the eyewear device 100 may construct a map ofthe environment surrounding the eyewear device 100, determine a locationof the eyewear device within the mapped environment, and determine arelative position of the eyewear device to one or more objects in themapped environment. The processor 432 may construct the map anddetermine location and position information using a simultaneouslocalization and mapping (SLAM) algorithm applied to data received fromone or more sensors. Suitable algorithms including particle filter,extended Kalman filter, and covariance intersection methods. Algorithmsthat apply machine learning in SLAM are also within the scope of theseteachings.

Sensor data includes images received from one or both of the cameras114A-B, distance received from a laser range finder, positioninformation received from a GPS unit, or a combination of two or more ofsuch sensor or other sensor providing data useful in determiningpositional information.

FIG. 6 depicts an example environment 600 for implementing naturalfeature tracking (NFT; e.g., SLAM processing). A user 602 of the eyeweardevice 100 is present in the environment 600 (which is a room in FIG. 6). The processor 432 of the eyewear device 100 determines its positionwith respect to one or more objects 604 within the environment 600 usingcaptured images, constructs a map of the environment 600 using acoordinate system (x, y, z) for the environment 600, and determines itsposition within the coordinate system. Additionally, the processor 432determines a head pose (position, roll, pitch, and yaw) of the eyeweardevice 100 within the environment by using two or more location points(e.g., three location points 606 a, 606 b, and 606 c) on one or moreobjects 604 or by using one or more location points 606 on two or moreobjects 604. The processor 432 of the eyewear device 100 may positionvirtual objects such as key 608 within the environment for augmentedreality viewing via image displays 180.

FIGS. 7A and 7B show a flow chart 700 depicting a method forimplementing augmented reality applications described herein on awearable device (e.g., an eyewear device). Although the steps aredescribed with reference to the eyewear device 100, as described herein,other implementations of the steps described, for other types ofdevices, will be understood by one of skill in the art from thedescription herein. Additionally, it is contemplated that one or more ofthe steps shown in FIGS. 7A and 7B and described herein may be omitted,performed simultaneously or in a series, performed in an order otherthan illustrated and described, or performed in conjunction withadditional steps.

At block 702, the eyewear device 100 captures images of the environment600 surrounding the eyewear device 100. The processor 432 maycontinuously receive images from the visible light camera(s) 114 andstore those images in memory 434 for processing. Additionally, theeyewear device may capture information from other sensors, e.g.,location information from a GPS sensor or distance information from alaser distance sensor).

At block 704, the eyewear device 100 compares objects in the capturedimages to objects in known images (previously captured images) toidentify a match. The processor 432 may compare object image data fromthe captured images stored in memory 434 to object image data of knownobjects in the object database 480 (FIG. 4B) to identify a match usingthe object identifier 482 (FIG. 4B), e.g., implementing a conventionalobject recognition algorithm or a neural network trained to identifyobjects. In one example, the processor 432 is programmed to identify apredefined particular object (e.g., a particular picture 604 a hangingin a known location on a wall, a window 604 b in another wall, and aheavy object such as a safe 604 c positioned on the floor). Other sensordata, such as GPS data, may be used to narrow down the number of knownobjects for use in the comparison (e.g., only images associated with aroom identified through GPS coordinates). In another example, theprocessor 432 is programmed to identify predefined general objects (suchas one or more trees within a park).

At block 706, the eyewear device 100 determines its position withrespect to the object(s). The processor 432 may determine its positionwith respect to the objects by comparing and processing distancesbetween two or more points in the captured images (e.g., between two ormore location points on one objects 604 or between a location point 606on each of two objects 604) to known distances between correspondingpoints in the identified objects. Distances between the points of thecaptured images that are greater than the points of the identifiedobjects indicate the eyewear device 100 is closer to the identifiedobject than the imager that captured the image including the identifiedobject. On the other hand, distances between the points of the capturedimages that are less than the points of the identified objects indicatethe eyewear device 100 is further from the identified object than theimager that captured the image including the identified object. Byprocessing the relative distances, the processor 432 is able todetermine the position within respect to the objects(s). Alternatively,or additionally, other sensor information, such as laser distance sensorinformation, may be used to determine position with respect to theobject(s).

At block 708, the eyewear device 100 constructs a map of an environment600 surrounding the eyewear device 100 and determines its locationwithin the environment. In one example, where the identified object(block 704) has a predefined coordinate system (x, y, z), the processor432 of the eyewear device 100 constructs the map using that predefinedcoordinate system and determines its position within that coordinatesystem based on the determined positions (block 706) with respect to theidentified objects, e.g., through SLAM processing. In another example,the eyewear device constructs a map using images of permanent orsemi-permanent objects 604 within an environment (e.g., a tree or a parkbench within a park). In accordance with this example, the eyeweardevice 100 may define the coordinate system (x′, y′, z′) used for theenvironment.

At block 710, the eyewear device 100 determines a head pose (location,roll, pitch, and yaw) of the eyewear device 100 within the environment.The processor 432 may determine head pose by using two or more locationpoints (e.g., three location points 606 a, 606 b, and 606 c) on one ormore objects 604 or by using one or more location points 606 on two ormore objects 604. Using conventional image processing algorithms, theprocessor 432 determines roll, pitch, and yaw by comparing the angle andlength of lines extending between the location points for the for thecaptured images and the known images.

At block 712, establish communication with a remote device when theposition of the eyewear device 100 reaches a predetermined locationwithin the environment. The remote device is configured to produce aphysical output. The processor 432 of the eyewear device 100 mayestablish communication with the remote device 402 via a transceiver(e.g., wireless circuitry 424/436). In one example, upon establishingcommunication, remote device 402 transfers an API to the eyewear device100 for use in controlling the physical output of the remote device 402.In other examples, the eyewear device 100 includes programmingpreviously stored in memory 434 for providing signals for controllingthe remote device 402 or the eyewear device 100 may retrieve suchprogramming from the mobile device 401 or server system 498 directly orvia a network 495.

The physical output, by way of non-limiting example, refers toelectromagnetic radiation (photons), sound, air flow or mass flow(particles, confetti, etc.). The predetermined location maybe selectedduring a setup procedure. The predetermined location can be selected byselecting particular image characteristics to be found (see block 704).The predetermined location can also be selected by identifying a marker,where the identification can be placed, during the setup in a video (oraudio) file, for example, in metadata.

At block 714, control the remote device to vary the physical output asthe position (location, orientation, or both) of the eyewear devicechanges within the environment. The eyewear device 100 controls theremote device 402 (e.g., via a retrieved API) to vary the physicaloutput responsive to movement of the eyewear device 100 within theenvironment. The eyewear device 100 may control the remote device 402responsive to its location (e.g., using techniques described above forblock 708), its orientation (e.g., using techniques described above forblock 710), or both location and orientation.

In one example, the physical output is controlled responsive to bothlocation and orientation. In accordance with this example, if thephysical output is an image of a sun 910 projected on a screen (see FIG.9B). Changing the location of the eyewear device 100, e.g., movingforward/backward, will change the diameter of the sub projected on thescreen, e.g., increasing/decreasing, while changing the orientation ofthe eyewear device 100, e.g., changing the yaw/pitch, will change thelocation of the sun on the screen, e.g., horizontal/vertical location.Also in accordance with this example, if the physical output is adirectional fan. Changing the location of the eyewear device 100, e.g.,moving forward/backward, will change the intensity of air flow, whilechanging the orientation of the eyewear device 100, e.g., changing theyaw/pitch, will change the direction of the air flow.

In another example, the physical output is controlled responsive to theorientation of the eyewear device 100 for as long as the location of theeyewear device 100 remains within a predefined area of the environment,e.g., within a predefined radius of the predetermined location withinthe environment resulting in establishing communication (see block 712).In accordance with this example, while the eyewear device 100 remainswithin the predefined area, the orientation/head pose of the eyeweardevice controls the physical output. When the eyewear device 100 exitsthe predefined area, the eyewear device 100 no longer controls thephysical output.

At block 716, optionally, present image overlays on the eyewear device100 to a user/wearer. The eyewear device 100 may add an augmentedreality feature associated with the physical output, e.g., rays 924emanating from a sun projected by a remote device 402 on a background,using optical assembly 180 under control of image display driver 442 andimage processor 412.

At block 718, the steps described above with reference to blocks 706-716are repeated to update the position of the eyewear device 100 as theuser moves through the environment 600.

FIG. 8 depicts a flow diagram of an example process for setting up theeyewear device 100 for use in a given environment. To set up the eyeweardevice 100, the eyewear device 100 or other device with similarlypositioned cameras, at block 802, captures images of the surroundingenvironment in which the eyewear device is going to be used along withlocation coordinates, and a map of the surrounding environment isconstructed. From the images and the map, at block 804, objects andfeatures are identified. This identification can be performed by taggingareas of the image at identified pixel locations. Alternately, a featurecan be associated with a marker, e.g., stored in a metadata header,described by proximity relationship to other features. The images/map ofthe surrounding environment and the identified object and features arestored in a digital memory at block 806.

FIGS. 9A, 9B, and 9C are images for use in describing one example. Inthe example shown in FIGS. 9A, 9B, and 9C, a user 902 wearing an eyeweardevice 100 enters an environment (e.g., a room of a warehouse in theillustrated example). The eyewear device 100 captures images within theenvironment. The eyewear device 100 identifies objects/features withinthe images such as a frame 906 and a screen 908. Using SLAM processing,the eyewear device 100 determines it's position (location/orientation)within the environment with respect to the object/features. When theeyewear device 100 reaches a predetermined location within theenvironment (e.g., X, Y, Z location coordinate 920), the eyewear device100 establishes communication with a remote device, e.g., a projector(not shown) projecting an image 922 on the screen 908. The eyeweardevice 100 then controls a physical output of the projector based on itsposition. For example, changing the orientation/head pose of the eyeweardevice 100 results in a sun 910 changing location on the screen 908 froma first location (FIG. 9B) to a second location (FIG. 9C).

Additionally, the eyewear device 100 may add an augmented realityfeature associated with the physical output, e.g., rays 924 emanatingfrom the sun 910, using optical assembly 180 under control of imagedisplay driver 442 and image processor 412.

In another example, a user wearing an eyewear device 100 captures imagesand information depicting another environment surrounding the eyeweardevice 100. When the eyewear device 100 reaches a predetermined locationwithin the environment with respect to a book on a stand (e.g., anassociated X, Y, Z location coordinate), the eyewear device 100establishes communication with another remote device, e.g., an air flowsource (not shown). The eyewear device 100 then controls a physicaloutput of the air flow source based on its position. For example,changing the orientation/head pose of the eyewear device 100 results ina puff of air from the air flow source that is directed toward the bookto turn a page in the book.

Any of the functionality described herein for the eyewear device 100,the mobile device 401, the remote device 402, and the server system 498can be embodied in one or more computer software applications or sets ofprogramming instructions, as described herein.
